[Tagging] Cattle bathroom

[santamariense]

Then, if amenity and farm is not for this type of thing, man_made
would be a good choice:

man_made=dip
dip=cattle, sheep, *

with useful combination:
building=roof
access=private, costumers

I had thought about amenity because here in Brazil seems there to be
communitary places for associated people to use plunge dips for their
cattle. After, another mapper remmembered me that man_made would be
aplicable for this.

@bryce2, Now I'm thinking to open a business like this you mentioned.
Good idea. (laughing) :-)
